DIP SPST Switch

The DIP SPST switches on the board are used for enabling and disabling various interfaces. Switch and
their functions are:

•

Audio Switch: Audio switch (SW15) is to enable the Audio buffer.

•

COM8 Switch: The COM8 switch (SW11) is to Enable/Disable COM8 Buffer.

•

LCD/HDMI Selection Switches: The LCD and HDMI selection switches (SW14 and SW13) is to select
between the LCD or the HDMI. In both OFF condition, the LCD will be functioning. In the ON condition,
the HDMI will be functioning.

•

UART0 over USB/DB9 Switch: This switch (SW12) is used to enable UART0 over USB. In the ON
condition, UART0 is over DB9 connector. In the OFF condition, UART0 is over USB.
